Well,
Just to let you know Specific Absorbtion Rate, or SAR as the cell phone companies and FCC (and other world regulatory bodies) call it, actually measures how much it heats the FLUID in YOUR brain to use said cellular telephone.
They set up an artificial head, and test the phone at its output.
Interestingly enough though there are controls in place for 'maximum' SAR ratings there is never any indipendant verification of the ratings, at least in the good 'ol US of A. So we are just trusting the telephone manufacturers that despite complaints of dropped calls and poor signal strength (signs of low power phones) they are still withing the legal limit.
P.S. I have a cell phone, I use about 1200 minutes per month, I dont have a land line, My phone's SAR rating according to Verzion Wireless's website is 1.45.
I dunno, there is a company called sarshield, I from my tests their product doesnt work, but they do have a nice list of SAR rates on their website, sarshield.com. I'm personally testing a product called a Green8 right now. They are made in germany and available at green8usa.com.
If you care at all.
Ta,
Ravi
